The overwhelming majority of Senate Democrats have come out against Supreme Court nominee Neil Gorsuch — with most planning to support a filibuster if it comes to that.

That means the Senate could be in for a showdown vote later this week.

With 52 Republicans and 48 Democrats in the chamber, the majority party needs eight Democrats to join them to break a filibuster (which takes 60 votes). All Republicans are expected to back the nominee. But if they can't get to 60, they could deploy the so-called "nuclear option" to lower the threshold and push through to confirmation on a simple majority -- a major change in Senate precedent.

So far, however, only three Democrats have come out saying they would support Gorsuch -- Sens. Joe Manchin of West Virginia, Heidi Heitkamp of North Dakota and Joe Donnelly of Indiana, and Sen. Michael Bennett, D-Colo., announced on Monday that he will not support a filibuster.

Here’s where the rest stand, not including those who have taken no position:
